Carl and Richard talk to David Dennison about his complete change of development career: From C# and .NET to Scala and the JVM! David talks about getting work at iTrellis, and their move to a services stack of Scala, Akka and Spray. The discussion focuses on the many things that are the same between the platforms, as well as the differences - it's all managed code in the end! David also talks about getting into the mindspace of the new platform he is working in, as well as dealing with entirely new development tools and infrastructure. Could you change platforms if the opportunity arose?
